ULN2803ADW - Darlington Transistor Array

Download the ULN2803ADW datasheet PDF. This datasheet also covers the ULN2803A variant, as both devices belong to the same darlington transistor array family and are provided as variant models within a single manufacturer datasheet.

Description

The ULN2803A device is a 50 V, 500 mA Darlington transistor array.

The device consists of eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.

The collector-current rating of each Darlington pair is 500 mA.

Features

  • 1 500-mA-Rated Collector Current (Single Output).
  • High-Voltage Outputs: 50 V.
  • Output Clamp Diodes.
  • Inputs Compatible With Various Types of Logic 2.
